- Removed LocaleList tests; updated other tests so they don't depend on LocaleList.
- Updated tests so they no longer assume that the prototype object of a constructor is an instance of that constructor.
- Updated tests so that jshint is happy.
- Removed @path attributes from test files; updated comment in packager.py explaining why they're unnecessary.
- Removed "use strict" statements, which interfere with strict/non-strict testing.
- Removed testcase functions, which are unnecessary.
